The two 125,000-ton passenger vessels, which are the largest ever
constructed for AIDA Cruises, feature many innovations that will set
higher standards in vessel environmental performance.

The Emsys continuous emissions monitoring system has a unique
laser-based emissions sensor, allowing high accuracy measurement for up
to 10 exhaust stacks.

The system also has the capability to measure smoke (Opacity) and
Particulate Matter (PM). The standard configuration measures NOx, SOx
and CO2, and has been awarded Type Approval by ABS to cover each of
these pollutants. Emsys can also be configured to report carbon monoxide
(CO) and methane (CH4).

These latter gases are not yet covered under IMO Regulations but are
seen as critical going forward, as the upward trend for using LNG as a
marine fuel may bring further challenges regarding air pollution.
